Abstract

The invention discloses a portable assembled shield tunneling machine sleeper and solves the technical problems that an existing shield tunneling machine trolley sleeper is low in stability and is easy to deform. The sleeper comprises a motor vehicle channel steel sleeper beam (15); the top of the motor vehicle channel steel sleeper beam (15) is provided with two pairs of motor vehicle rail clamping grooves (18), pads are arranged between the left and right bottoms of the motor vehicle channel steel sleeper beam (15) and a first lining segment (2), lining segments of left and right sides of the motor vehicle channel steel sleeper beam (15) are provided with arc plates, and the arc plates are fixed to longitudinal segment connecting bolts through arc plate tail unit fixing sheets; shield tunneling machine trolley rail grooves are arranged on the tops of left and right vertical plates; the sides of the left and right vertical plates are movably connected to the sides of the motor vehicle channel steel sleeper beam (15) in a pressed manner. The shield tunneling machine trolley sleeper and a slag conveying motor vehicle sleeper can be assembled accurately and safely, the portable assembled shield tunneling machine sleeper can be assembled and disassembled in site particularly, and the sleeper material consumption is reduced.

Description

technical field [0001] The invention relates to a sleeper of a shield machine, in particular to a sleeper which is easy to disassemble and combine when using a shield machine in the excavation process of a subway tunnel. Background technique [0002] In the construction process of shield tunneling, the shield machine excavates the soil to form the tunnel body, and then uses the assembly machine to assemble the segments. Special connecting bolts are used to connect the segments in the circumferential and longitudinal directions. Secondary grouting is performed on the reserved grouting holes to form a closed annular lining support system to achieve a force balance between the tunnel support system and the surrounding soil. During the tunneling process of the shield machine, it is necessary to lay trolley sleepers that can meet the needs of shield trolleys and electric locomotive sleepers that can meet slag and segment transportation. At first, the sleeper of the shield machin...
